Formula / how it works
Each discount applies to the remaining price: P1 = P0(1−d1), P2 = P1(1−d2), … Not the same as summing percents. Business calculators use standard managerial / accounting identities (break-even, margin, markup, ROI, hourly↔salary). They ignore taxes, inventory write-offs, benefits loading, and financing unless a field explicitly includes them. For the Stacked Discount Calculator, the labeled fields (List price (money), First discount % (%), Second discount % (%), Third discount % (optional) (%)) drive the live result panel.

What this calculator is
Stacked discounts are multiplicative, not additive — 20% then 10% is not 30% off. MyCalcsWorld’s Discount Stack Calculator applies sequential percent offs so shoppers and merchandisers see the true final price. Pair with the single Discount and Margin/Markup tools for simpler cases. Educational retail math — promo rules can add exclusions. MyCalcsWorld keeps inputs labeled and formula notes visible so you can mirror the same scenario on paper when you need an audit trail. Core results run in the browser with no signup required for the calculator itself.
When to use / who it helps
- Checkout with two promo codes.
- Teaching why percents do not add.
- Merchandising stacked sale checks.
- Comparing stack vs single equivalent percent.
- Invoice vendor multi-discount lines.
How to use
Steps
- Enter original price.
- Enter first discount %.
- Enter second and third as needed.
- Read final price and total % off.
- Compare to a single equivalent discount.
- Confirm POS order of operations.
How to interpret results
- Order usually matters only with caps/fees; pure percents commute.
- Effective % off = 1 − Π(1−di).
- Educational retail math.
- Tax may apply after discounts.
- Not a coupon legality checker.
Common mistakes & gotchas
- Adding percents instead of chaining.
- Applying discounts to tax-inclusive bases wrongly.
- Forgetting a third discount field at 0.
- Mixing coupon order when rules are non-commutative with caps.
- Ignoring shipping that is not discounted.
Worked example
Worked example — 200 with 20% then 10%
- After 20%: 160.
- After 10%: 144.
- Effective off = 28%, not 30%.
- 200 × 0.8 × 0.9 = 144.
Result: 200 with 20% then 10% ends at 144 — 28% effective off, not a 30% single markdown.
